Droop, NuteBurn? Please help (pics)

She has been doing great until last night today. When i woke this morning i seen that she is very droopy and some of her leaves almost look burnt and maybe to dark of a green color. I didnt feed her for 3 1/2 days because i was gone on business and im hoping that this is just because she was hungry. She is one week into 12/12 and she is in roots original organic soil and im feeding her 2 table spoons of biogrow and biobloom. it calls for 1.5 to 3 tablespoons on the label. Using a 600 w HPS.

My best guess is that you have a N toxicity and possible have overwatered.

Very much looks like excess N to me also, if you just flipped to flower, i believe you will be fine as long as you gradually back off the N and give the proper P-K value. No expert though, pretty sure someone will chime in.

looks very dark mate so agree with insidagain and spl over n

I highly doubt i have overwatered because i didnt water for almost four days and the pot was veryy light i usually water every two days. I am going to look into this N deficiency.

On the other hand when i got home i fed and watered and they seem to have sprung back up so im guessing they were just starving/under watered. plant is still dark but the new growth looks very healthy green.

It's looks, at least from a few of the pics that new growth is looking better. Youve probably already corrected what was going on. I left my plants for 4 days due to family emergency and when I came back they looked shitty, but they came around pretty fast.

N toxicity! Not deficiency! Dont just add N though, triple check! Your old leaves are really dark and slightly clawed, which honestly doesnt look too bad because nobody wants early yellowing leaves during flower. looks like it will hold through in flower if you transistion your nutes properly (first 3 weeks flower). All your new growth on the top is lighter because its just new growth, it will darken naturally when it matures, but you have to keep an eye here for burnt tips or clawed tips or any deficiency.

To my understanding the bottom foliage will stay that color untill your plants need more nutrients that are not available through the root zone. Then your new underfed growth will take the excess nutes from the leaves with the most nutrients first, slowly killing them off at the same time. If you ask me, they are "just a tad" overfed with nitrogen. As long as your tips aren't browning and burning you will be fine. Do not up ypur nitrogen ratio unless she ask for it. Whatever your feeding keep it the same or back it off just a tad. Your plant will want to consume more and more amounts of nutrients over time, so its a bit tricky not to overfeed when it has already been overfed, ypu have to find exactly what the plant likes by watching new growth. What would i do in this situation? If it is overwatered i will let it dry out 80% before watering again. Many people say its okay to let it wilt first then water, if your like me and never over-water then its quite easy to kill it by under-watering because you will be used to waiting 4 days for it to wilt, then onc week your roots kick off and the pot will get empty every 2 days instead of 4 eventually. I have lost plants before by just 48hrs of no water after forgetting to water just 1 time, it even "seems" i have stunted my flowering plant by letting it wilt twice from underwatering.

What nutes are you using? What soil? Distance from 600w hps?
